ATDH1150USB ATF15xx CPLD JTAG ISP Download Cable
USER GUIDE
Introduction The Atmel® ATF15xx Complex Programmable Logic Device (CPLD) USB-based JTAG ISP Download Cable [Atmel PN: ATDH1150USB] connects to a standard USB port on a host computer on one side and to a JTAG header of a programming circuit board on the other side. It transfers the JTAG instructions and data generated by the ATMISP software running on the host PC to the Atmel ATF15xx series CPLDs on the programming circuit board. The ATMISP software can be downloaded from the Atmel website at http://www.atmel.com/tools/ATMISP.aspx. With this In-System Programming (ISP) download cable and the ATMISP software, design changes can easily be downloaded directly to the ATF15xx JTAG devices, resulting in easy prototyping of designs. The ATDH1150USB cables are made by two vendors and have identical circuit design. The cables labeled with “ATDH1150USB-K” are built by Kanda (www.kanda.com) and can also be purchased directly from Kanda. When purchasing this cable from Atmel or an Atmel distributor, the Atmel ordering code is “ATDH1150USB”.
Features
Supports Industry Standard IEEE 1149.1 (JTAG) Compliant Devices Allows Users to Perform JTAG ISP of Atmel ATF15xx CPLDs Supports Target Systems Using 5.0V, 3.3V, 2.5V, or 1.8V VCC and I/O Standards Supported by the ATMISP Software (Version 6.6, 6.7, and 7.x) Interfaces with a Standard USB 2.0/3.0 Port on a PC Supports 10-pin and 14-pin JTAG Interface Headers (JTAG-A and JTAG-X)
Supports The ATDH1150USB ISP Download Cable supports all ATF15xx CPLDs with the JTAG feature enabled. By default, the ATF15xx CPLDs are shipped with the non-volatile memory in the erased state, which would enable the JTAG feature. Once the JTAG feature of an ATF15xx is disabled by programming it with a JEDEC file that disables the JTAG feature, its memory contents can no longer be accessed via the JTAG port. To re-enable the JTAG feature, the ATF15xx CPLD will need to be erased on a standalone device programmer.

Functional Description The ATDH1150USB ISP Download Cable connects to the PC host’s USB port on one side using the USB cable provided to communicate with ATMISP. On the other end, the cable is connected to a 10pin or 14-pin JTAG header on the programming circuit board using the 10-wire ribbon cable provided or a 14-wire ribbon cable (not included) to communicate with the target JTAG devices. Users can choose to use either one of the two JTAG connectors (JTAG-A and JTAG-X) available on the ATDH1150USB based on their requirements; however, these two JTAG connectors should not be used at the same time. The second 10-pin header labeled TWI on the ATDH1150USB is not supported and should not be used. A functional block diagram of the ATDH1150USB ISP Download Cable is shown in the below figure, and Table 1 and Table 2 provide the pin assignments and signal descriptions for the two JTAG connectors.

The ISP circuit board must supply VCC and GND to the ATDH1150USB ISP Download Cable through the 10-pin or 14-pin JTAG header via the VCCT and GND pins. A regulated VCC voltage between 1.65V to 5.5V is required, and it should be the same VCC supply used by the JTAG devices.

The multi-color status LED on the ATDH1150USB ISP Download Cable displays the status of the JTAG communication and operation:
Green = Successful JTAG communication and operation. Red = Unsuccessful JTAG communication and/or operation. Amber = JTAG operation is in progress.
The programming circuit board must provide a regulated VCC to the ATDH1150USB ISP Download Cable via the VCCT pin of the 10-pin or 14-pin JTAG header. The ATDH1150USB ISP Download Cable VCCT must be between 1.65V and 5.5V at 150mA (max) of current, and it powers the output buffers for the JTAG signals. The host PC's USB port must also supply a VCC (VBUS) which is in compliance with the USB 2.0/3.0 specification to the ATDH1150USB ISP Download Cable via Pin 1 of the USB connector. Furthermore, a stable GND from the programming circuit board and USB port must also be provided to the ATDH1150USB ISP Download Cable. The color stripe on the ribbon cable of the ATDH1150USB ISP Download Cable indicates the orientation of Pin 1 of the JTAG female connector. The color stripe or a polarized header can be used as a guide to assure the female connector is properly oriented when it is attached to the programming circuit board. The below figure illustrates the pinouts of the 10-pin and 14-pin female connectors on the ATDH1150USB ISP Download Cable. The pinout of the JTAG male header on the programming circuit board must match one of the pinouts shown. Figure 2.

Frequently Asked Questions
For a multiple device JTAG hardware chain, which device is considered the first device (Device #1) when setting up the Atmel CPLD ISP (ATMISP) software? The device with its TDI pin connected to the TDI pin of the JTAG header is the first device (Device #1) of a JTAG chain. The device with its TDO pin connected to the TDO pin of the JTAG header is the last device of the chain.
For devices with different VCCINT and VCCIO supplies, which VCC (VCCIO or VCCINT) should be used to supply the ATDH1150USB ISP Download Cable's VCCT? VCCIO should be used to supply the VCCT of the ATDH1150USB ISP Download Cable.
Can a JEDEC file with the JTAG port feature disabled be programmed into the ATF15xx through JTAG ISP? Since all ATF15xx devices are shipped in a blank (erased) state, the JTAG port is enabled by default. Therefore, they can be programmed with a JEDEC file with the JTAG port feature disabled ONLY ONCE via JTAG ISP. However, this is not recommended since the pins used for the JTAG port of the ATF15xx devices can become outputs immediately after programming is completed and they can content with the output drivers in the ATDH1150USB ISP Download Cable. Furthermore, please note that once the JTAG port is disabled, the device can no longer be accessed through the JTAG port. To re-enable the JTAG port, you must erase the device or re-program the device with a JEDEC file with the JTAG port feature enabled using a stand-alone 3rd-party device programmer from vendors such as BPM Microsystems, Data I/O, Hi-Lo Systems,. etc.
